T0 all whom z't may concern:

Be it known that I, JOHN W. GEARHART, a citizen of the Unitecl Staates,residing at Fresno, in the county of Fresno and Staate of California,have invented new and useful Improvements in Line-Markers, 0f whichinafter fully described;

the following is a specification.

The invention relates to a line marker for use in copying manusoript,printed matter, stenographic ciphers, or the like.

The prima.ry object of the invention is the provision of a marker ofthis character wherein the same can be supported and clamped to thepages 0f a memorandum book 130 lie transversely of the exposed face ofthe uppermost page, and is capable of ready anc1 asy acljustment t0enable the user to observe with accuracy a particular line on said pageduring the act of copying.

Another object of the invention is the provision of a marker wherein thesame can be held firmly 011 the memorandum book and is readily adaptablet0 books 015 varying widths, and which may be moved length- Wise of apage when the book is open to insure the reading 0f each line to becopied With certainty and accuracy.

A further object of theinvention is the provision of a nmrker 0f thischaracter which is extremely simple in construction, readily and quicklymounted in.position on anal removed from a book, conveniently and.easily adjusted relative 130 the iines 011 a given page therein, streng,yet light in weight, durable, reliable and eflicient in its purpose, andinexpensive in manufacture.

With these and other objects in view, ehe invention consists in theconstruction, combination and arrangement of parts as Will behereinafter fully describd illustrated in the accompanying drawing, andpointed out in the claim hereu.nto appended.

In the drawing: Figure 1 is a perspective' view of an open memorandumbook showing the marker constructed in accorolance With the inventionapplied. Fig. 2 is a longitudinai sectional view through the marker.Fig. 3 is a vertica1 transverse sectional view. Fig. 4 is a sideelevation.

Similar reference characters indicate C01- responding Parts throughoutthe several views in the drawing.

' Referring to the drawing in detail, A dsignates a memor;1 ndum o1 noteb00k, which is of the usual Wel1-known construction, having therein theusual 1ined pages B, over the exposed face f a given one of Which isadapted to traverse the marker C here- "The marker comprises a basemember 5 preferably made from metal, in the form of a strip havingupwardly and inwardly The sections 7 ab their inner adjacent ends' a1 eintegrally connected through th e med1um of a spiral resilient -loop 9which tends t0 move the sections toward. euch other, yet permitting thesame to spread under tensioi1 so that the jaws or ears 8 Willfrictionally bind theside edgesof a series of the pages B of the book A,and this loop also serves as ahand hold to permit the shifting of themarker longitudinally 0f the page to ahne with any 0ne of the lines 011the eXposed face of the outermost 01' ppermost page, thereby enabling apeison to rea d. a particular line with accuracy When in the act ofcopying from the book.

The flanges 6 overlie the sections 7 to guide the same in their slidingmovement upon the base 5, the loop 9 being formed with cut-away portions10 120 form a clearance for the flanges 6 so as not to bind 01"interfere w'ith the niovements of the sec" tioris, Which are tensioned.by the said p.

F1Om the foregoing description taken in connection with the accompanyingdrawing, it is thought that the constructiqn z nd manner ofuse of thedevice Will be clearly understood, am]. therefore a more extendedexplanation has been omitted.

What is claimed is:

A line marker of the dass described comprising an elongated base ofuniform width throughout its length and having guide flanges at itslonger edges, slidable sections In testimony whereof I, affix mysignamounted upon the base and engaged by the ture in presence of twowitnesses.
